Predicted to enable DNA binding activity. Predicted to contribute to DNA-directed 5'-3' RNA polymerase activity. Predicted to be involved in transcription by RNA polymerase II. Predicted to be located in nucleoplasm. Predicted to be part of RNA polymerase I complex; RNA polymerase II, core complex; and RNA polymerase III complex. Is expressed in several structures, including branchial arch; limb; maxillary process; nervous system; and sensory organ. Orthologous to human POLR2E (RNA polymerase II, I and III subunit E).
